method of determination of u0441u0430u043cu043eu043fu043eu0433u043bu043eu0449u0435u043du0438u044f gamma radiation in the radioactive source, comprising measuring the coefficient of radiation u0432u0435u0449u0435u0441u0442 u03bc wa source (e), the preparation of three-dimensional calibration source with the same shape and size as the source, which is the definition of sa u043cu043eu043fu043eu0433u043bu043eu0449u0435u043du0438u044f,changes in absorptive capacity calibration source by inert gas based on a fact that, in order to simplify the method and increasing the the range of its use, for all values of the u03bc (e) were measured on a gamma ray count rate at the peak of the gcms uptake from three-dimensional calibration the source in the presence of the gas, and in his absence.and u0441u0430u043cu043eu043fu043eu0433u043bu043eu0449u0435u043du0438u0435 source defined by u0444u043eu0440u043cu0443u043bu0435u0433u0434u0435 in (e) - u0441u0430u043cu043eu043fu043eu0433u043bu043eu0449u0435u043du0438u0435 in the source of gamma quantum of energy Eu043eu0442u043d.u0435u0434.u03bc; (e) - coefficient of gamma quantum of energy Eu0432 substance content of cm, n - speed account at the height of the full absorption of three-dimensional u0440u0430u0434u0438u043eu0430 u043au0442u0438u0432u043du043eu0433u043e source with variable absorptive capacities in the absence of its gas, c; n is the same, with a source of gas mass (m, c, u03bc - coefficient u043eu0441u043b u0430u0431u043bu0435u043du0438u044f gas u0434u043eu0437u0438u0440u043eu0432u0430u043du043du043eu0433u043e in sourceunder normal circumstances, see; v is the volume, which takes the gas mass. normally, in the absence of a sorbent, see; v is the internal volume of the container (amount of substance, the fec u0441u0438u0440u0443u044eu0449u0435u0433u043e gas).
